vThis invention relates to winding machinesin which the yarn or threadmay be wound into either conical or cylindrical packages as desired, said machine being commonly known as a cone and tube winder. In thistype of machine it has heretofore been common to provide the cam which controls the reciprocating ,motion of the two traverse guides for the yarn or thread on opposite sides of the machine with three cam grooves, the two outer cam grooves being used when winding the conical packages or cones and the middle cam groove belng used when winding cylindrical packages or tubes; it being understood that the cam grooves for cone winding are shaped differently from the cam groovefor tube winding. An example of this type of machine is illustrated in United States Letters Patent No. 1,353,475, dated September 21st, 1920. This three specia traverse guides for each class of winding or traverse guides havingremovable and changeable cam" groove shoes. It also necessitates the spacing of the winding units sufliciently far apart to accommodate the wide cams necessary to provide the three .cam grooves therein;

' he object of my invention islto provide means whereby the width of these traverse guide actuating cams may be materially lessene-d by utilizin a single cam groove, the

opposite side wa ls of which are shaped to control the reciprocating movement of the traverse guide for cone winding when the cam is rotated in one direction and to control.-

the reciprocating movement of the same traverse guide for tube winding when the cam is rotated in the opposite direction. This arrangement permits of a very great saving of s ace by allowing the windingunits to;

be p aced closer together than heretofore in this type of machlne and also permits of a great saving in expense by eliminatingthe cutting of the'two additional cam grooves in 7 each cam. It also permits the use of a standard thread i'de arranged in a common position for 0th classes of w1nd1ng.

A- practical embodiment ofmy invention is representedin the accompanying drawings, in which- Fig. 1 represents in side elevation a POI tion of a.winding machine at the drive end oove cam necessitates the making of thereof with my improved cams applied thereto. Fig. 2 represents an end elevation with the drive arranged for 'cone winding.

The shaft 1 for each row of traverse guide actuating cams 2 is rotatably mounted in the machine frame and means are provided for rotating these cam shafts in .one or the other direction, as follows; i w

The main drive shaft 3 herein shown as driven from an electric motor 4 carries a cone pulley 5 which'drives,through a belt 6,"

two gears 13 and 14 being carried by an arm 'A gear 12 on the shaft 8 meshes with a gear 13 which also meshes with a gear 14, the

9 rotatably adjustable on the hub of the shaft 8. The cam shafts 1 upon opposite sides of the machine are provided ,with intermeshlng gears 15 16. When it is desired to drive the cam shafts in" the, direction for cone winding, the arm 9 is rocked to bring the gear 13 into mesh with the. gear 15 an when it is desired to drive the cam shafts in the opposite direction for tube winding, the arm 9'is rocked to bring the gear 14 into mesh with the gear 15, this movement bringing the gear 13 out of mesh with the gear 15, it still remaining mesh with the gear The usual winding rolls 17 for the cones or tubes, along each side of the machine are carried by the shafts 18. One of the winding roll shafts 18 is driven from the drive shaft 3 through the pulley 19, belt 20 and pulley 21', while the other winding roll shaft 1s driven from the drive shaft 3 through the winding conical packages,

The traverse guides for the thread or yarn are denoted b 25, which guides reciprocate in the usua manner on the-bars 26, 27. Each of these guides is provided with a stud or roller 28, arranged to coact with a single circumferential cam groove .29 in its actuating cam 2, for cone or tube winding asfollows: i The side walls of the cam groove 29 at 30 and 31 for one-half of the circumference of the cam are shown as substantially parallel and for the other half of the circumference the side walls at 32, 33 are shown as provided with progressively increasing pitches in opposite directions; With the side walls ofthe cam groove thus shaped, when the traverse guide will be accelerated when traveling toward the small end of the package for laying less yarn at the point of the package than at the base, causing it to gradually increase-in taper as it builds up and when windingcylindrical packages, the traverse guide acceleration is reversed on one-half of the camto neutralize the density of the winding for building up the package equally- In other types of cone and tube winding, the shape of the side walls will be changed to. suit.

It will be noted that the stud or roller 28 of the'traverse guide at the opposite limits of' its movement quite closely fits between the side wallsof the cam grooves, therebyv preventing pounding and ensuring the proper throwing of the yarn at the ends of In operation When it is desired to wind a conical package, each cam 2 1s drlven 1n a direction which will cause the stud or .roller 28 of the traverse guide to travel along the sidewall portions 33, 30 of the cam.

groove 29. When it is desired to wind a cylindrical package, the movement of 'the cam 2 is reversed, thus causing the stud or roller 28 of the traverse guide to travel'along the side wall portions 32, 3l of the cam' groove29.-' V

In the present instance I have shown the winding machine in Fig. 1 as provided with cone holders 34 and the parts arranged for cone winding. Of course when it is desired to wind tubes, suitable tube holders will be employed.
